2025. I would now like to turn the conference over to John Marchetti, VP of Corporate Development and Head of Investor Relations. Thank you, and good afternoon, everyone. I'm John Marchetti, nLIGHT's VP of Corporate Development and the Head of Investor Relations. With me on the call today are Scott Keeney, nLIGHT's Chairman and CEO, and Joe Corso, nLIGHT's CFO. Today's discussion will contain forward-looking statements, including financial projections and plans for our business, some of which are beyond our control, including the risks and uncertainties described from time to time in our SEC filings. Our results may differ materially from those projected on today's call, and we undertake no obligation to update publicly any forward-looking statement except as required by law. During the call, we will be discussing certain non-GAAP financial measures. We have provided reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures in our earnings release and in our earnings presentation, both of which can be found on the Investor Relations section of our website. I will now turn the call over to nLIGHT's Chairman and CEO, Scott Keeney. Scott? Thank you, John. Our first quarter results represent a strong start to 2025, with revenue, gross margin, and adjusted EBITDA all above the high end of our guidance range. The outperformance was primarily driven by another quarter of record defense revenue, which represented more than 63% of total sales in the quarter, up from 49% in the same quarter a year ago. Furthermore, this growth was supported by significant expansion in our defense product sales, which grew more than 150% year over year. We are uniquely positioned to drive continued growth in A&D, with leading high-power laser technology developed over the past two decades across the entire technology stack from chips to full laser systems, which is supported by our U.S. manufacturing sites. Our products in A&D are also well aligned with many of the Department of Defense's most critical priorities, such as directed energy and laser sensing. During the first quarter, we delivered strong results in each of these critical markets. Directed energy lasers complement traditional kinetic defenses by offering a deep magazine, low cost per engagement, and speed of light delivery. These systems can neutralize a wide range of targets, including drones, rockets, artillery, mortars, and missiles, while also rebalancing the economics of protecting key assets. We continue to make progress on our HELSI- 2 program. As a reminder, this is a $171 million DOD program to develop a 1 MW high-energy laser, with a completion date expected in 2026. The shipment of critical components towards this program was a significant driver of our record defense product revenue in the quarter and is expected to be a substantial contributor to the growth through the remainder of the year. Our work on the Army's DE M-SHORAD effort, which is programmed to develop a 50 kW high-energy laser for short-range air defense, continues to progress, and we expect to complete our work on this contract in the middle of the year. The success we have achieved to date in key programs reinforces the importance of our vertical integration strategy in the directed energy market, where we leverage our entire technology stack to deliver the highest performing and most cost-effective high-energy lasers. This success has increased interest in our directed energy capabilities both domestically and among our international allies. In the U.S., we continue to respond to RFPs and RFQs associated with the President's Golden Dome Executive Order, which specifically highlights non-kinetic missile defense capabilities as an area for development. With a mandate to build these systems in the United States, we believe we are well positioned to benefit from this effort over the coming years. Internationally, our work to support the Israeli Iron Beam program is progressing, and we have a growing pipeline of new opportunities that we expect to begin closing in the coming quarters. We have generated revenue at nearly every level of vertical integration in the directed energy market, and we have established ourselves as one of the most comprehensive suppliers to the U.S. government, other prime contractors, and foreign allies. We also continue to gain momentum in our laser sensing markets. Our laser sensing products include missile guidance, proximity detection, range finding, and countermeasures, and have been incorporated into several significant and long-running defense programs, all of which remain key defense priorities under the current administration. Our historical performance on these programs and our early success on multiple classified programs have created many new opportunities for us in this market. Over the last several quarters, we have bid on multiple new programs that have increased both the number of opportunities and the size of our sensing pipeline. In addition, further opportunities under the Golden Dome Initiative have emerged and could become a significant contributor to our growth in defense in 2026 and beyond. The solid start to the year, combined with our growing pipeline of both directed energy programs and laser sensing opportunities, gives me increased confidence that we can grow our revenue in aerospace and defense by at least 25% in 2025. Turning to our commercial markets, overall, our industrial and microfabrication markets remain challenging, though we did see some improvement compared to last quarter. The sequential growth in our commercial markets was driven by an increase in microfabrication sales as operations at our Thai contract manufacturing partner have stabilized, enabling us to satisfy customer demand. While we are pleased with the stabilization of manufacturing, demand is expected to remain weak through the remainder of the year. Longer term, we remain optimistic about opportunities for growth in metal additive manufacturing, particularly within the aerospace and defense markets, as they look to accelerate prototyping timelines and build resiliency into supply chains with domestic capabilities. Before I turn the call over to Joe to review our first quarter financial results, I'd like to briefly touch on the topic of tariffs. We have spent a significant amount of time over the last couple of months evaluating many different scenarios, and while there continues to be a significant amount of debate and uncertainty around what the tariff landscape will ultimately look like, the impact of these extraordinarily high tariffs on the overall economy, demand from our customers, and material costs for our products, there are a few comments I would like to make. First, we do not expect a significant impact on our business in defense over the long term. Over the short term, however, there may be some margin variability in our defense products as a result of the tariffs placed on some of the important materials used to manufacture these solutions. While the ultimate impact of tariffs on these products is still to be determined, we do not expect them to have a significant negative effect on our demand or long-term profitability of these solutions. Outside of defense, we have shifted the production of our commercial lasers from Shanghai, which we closed in late 2024, to our automated facility in the Pacific Northwest and to our contract manufacturing partner in Thailand. Our ability to shift manufacturing between the U.S. and Thailand should enable us to better manage tariff-associated risk. In summary, I'm pleased with the strong start to 2025, particularly around the ramp of our defense products, and I'm increasingly confident about the long-term growth in A&D based on our unique leadership across the technology stack for high-power lasers. Let me now turn the call over to Joe to discuss our first quarter financial results. Thank you, Scott. Total revenue in the first quarter of 2025 was $51.7 million, an increase of 16% compared to $44.5 million in the first quarter of 2024. Aerospace and defense revenue was $32.7 million in the quarter, up 50.4% year over year and 8.6% sequentially. Growth in the quarter was driven by increased defense products revenue, which increased more than 150% compared to the same quarter a year ago, primarily due to increased deliveries of components into our HELSI- 2 directed energy laser program. We expect A&D revenue to grow sequentially in the second quarter of 2025, and as Scott mentioned earlier, we feel increasingly confident that full-year revenue from our A&D markets should grow at least 25% year over year. First quarter revenue from our commercial markets, which includes industrial and microfabrication, was $19 million, a decrease of 16.8% year- over- year, but up 9.9% sequentially. Revenue from these markets was largely in line with expectations as industrial demand remained weak, and the quarter-over-quarter improvement in microfabrication sales was largely a result of our manufacturing partner being able to satisfy orders that had been previously unable to ship. Product revenue for the first quarter was $35.7 million, an increase of 21.5% compared to $29.4 million in the first quarter of 2024. The year-over-year increase in product sales was due to growth in defense product revenue, partially offset by a decline in commercial revenue. Development revenue of $16 million in the first quarter increased 5.4% compared to the same quarter a year ago. Total gross margin in the first quarter was 26.7% compared to 16.8% in the first quarter of 2024. First quarter gross margin included approximately a $1.9 million benefit related to duty reclaim. Excluding the impact of this benefit, total gross margin for the first quarter would have been approximately 23%, which is still above the high end of our guidance range, as both product gross margin and development gross margin were ahead of expectations. Product gross margin in the first quarter was 33.5% compared to 20.9% in the first quarter of 2024. First quarter product gross margin was positively impacted by higher product volumes, a favorable mix, and duty reclaim. Development gross margin was 11.5% compared to 8.9% in the same quarter a year ago. The upside in development gross margin was largely a result of program mix in the quarter. Going forward, we still expect development gross margin to remain in the 8% range. Operating expenses were $23.4 million in the first quarter compared to $22.2 million in the first quarter of 2024. Non-GAAP operating expenses were $17.8 million in the first quarter, a slight increase compared to $17.2 million in the first quarter of 2024. GAAP net loss for the first quarter was $8.1 million, or $0.16 per share, compared to a net loss of $13.8 million, or $0.29 per share in the same quarter a year ago. Adjusted EBITDA for the first quarter was $116,000 compared to a loss of $4.9 million in the first quarter of 2024. Turning to the balance sheet, we ended the first quarter with total cash, cash equivalents, restricted cash, and investments of $117 million. During the quarter, we drew down $20 million from our $40 million line of credit. Given the ongoing uncertainty surrounding the impact of tariffs and our expectation for increased working capital needs to support the growth in our A&D markets, we thought it was prudent to put a cash buffer in place on our balance sheet. Inventory increased to $43.8 million at the first quarter compared to $40.8 million at the end of 2024. The increase in inventory is primarily to support the forecasted ramp in directed energy products. Turning to guidance, based on the information available today, we expect revenue for the second quarter to be in the range of $53 million-$59 million. The midpoint of $56 million includes approximately $38 million of product revenue and $18 million of development revenue. We expect A&D revenue in the second quarter of 2025 to increase sequentially and year over year, and weakness in our industrial and microfabrication markets to continue throughout the year. Turning to gross margin, product gross margin in the second quarter is expected to be in the range of 27%-33%, and we expect development gross margins to be approximately 8%, resulting in a total gross margin range of 19%-25%. As we've mentioned previously, as a vertically integrated manufacturing business, gross margin is largely dependent on production volumes and absorption of fixed manufacturing costs. In addition, we are navigating a highly uncertain global trade market. While we do not expect a significant negative impact to our margins in the second quarter, we could experience further margin pressure in subsequent quarters if the current structure and level of tariffs remain in place for the rest of the fiscal year. Finally, we expect adjusted EBITDA for the second quarter to be in the range of approximately - $4 million to + $1 million. We continue to expect break-even adjusted EBITDA with quarterly revenue in the $55 million-$60 million range. With that, I will turn the call over to the operator for questions. Thank you. Ladies and gentlemen, we will now begin the question and answer session. Should you have a question, please press star followed by the number one on your touch-tone phone. You will hear a prompt that your hand has been raised. Should you wish to decline from the polling process, please press star followed by the number two. If you are using a speakerphone, please lift the handset before pressing any keys. Your first question comes from Jim Ricchiuti of Needham & Company. Please go ahead. Hi, thanks. Good afternoon. Maybe to start off with, can you talk to us about the line of sight you have to the product sales in A&D looking past Q2? I mean, you've talked about the growth you're expecting in A&D for the full year. I'm just trying to get a sense as to what kind of visibility you have to product sales. Hello? All right. Jim, can you hear me, Jim? I can. Scott, did you get that question? Should I repeat it? I apologize for the audio problems. Thanks for the question, Jim. I think, as we noted in our comments, the Healthy program is certainly one of the drivers of the product revenue. Certainly, we have visibility with respect to that program. We certainly have also increasing both orders and a funnel of opportunities and products that further contribute to our outlook to continue to improve defense broadly, but products in particular. And that 150% growth in the quarter was certainly one of the highlights for the quarter. Good. On the tariff, the issue of tariffs, help us understand where you could be impacted more. Is it in the microfabrication business? Is it relating to the production in Thailand? Maybe just in broad strokes, how should we think about that going forward, assuming the situation does not change or improve? Yeah. Hi, Jim. This is Joe. I'll take that one. The area where we will be affected most, frankly, is where the input costs are coming in from China today, and that disproportionately affects our industrial fiber laser business. But remember, as we think about where we are right now, we're still sitting on some inventory and the like. We do not expect a big impact at all in the second quarter. As we go throughout the year, depending on what the situation is and where these tariff rates ultimately shake out, it could have an impact in Q3 and Q4. We are not talking about anything that we feel today is significant, right on the order of a couple hundred basis points. Okay. Are you more concerned about the potential indirect impact as it relates to just demand across some of the markets in the commercial side of the business? Yeah. I think that is the thing that gives us pause. It is just how are these dramatic increases in tariffs going to affect broader markets indirectly? That is something that we cannot possibly forecast. Our business, especially with the defense business, has a relatively more insulated impact. Thank you. Your next question comes from Greg Palm of Craig-Hallum. Please go ahead. Yeah. Thanks. I had some issues joining. If you've already talked about some of this stuff, apologies. You kept your A&D outlook the same, but I think you mentioned you're increasingly confident. I guess what's changed in the last couple months, and what would you need to happen or see for you to actually increase the full-year guide at some point this year? Yeah. Good. Thanks, Craig. Sorry about the audio problems. Good question. We continue to see traction in not only the U.S., but also international markets for directed energy and our other applications. I think that's a theme that we will continue to provide more information as we can release more information there. As we just talked about, the tariffs certainly add some degree of uncertainty in the global environment, and it's just hard to determine what that's going to be. Again, it's not something that is going to directly affect us as much as perhaps others, but it certainly is a question mark in terms of how the overall economy continues to progress. Can you address what the tariff-related risk is specifically for A&D? I know you mentioned the input cost in China on the, I think, more on the sort of the industrial fiber laser business, but is that something that impacts everything? Yeah. I mean, we think about certainly where we buy our products, and certainly we don't have significant exposure there from China. But I know your suppliers have secondary exposure, right? That's where it's difficult to fully address how those tariffs are going to flow through the broader supply chains. It's more of that. Okay. And just to be clear, I mean, whether it's you or some of your suppliers, I mean, are there secondary sources outside of China if the current tariff rate sticks? What's everybody doing to mitigate that risk? I mean, as we talked about in our comments, certainly we're pleased that we have our operations running in Thailand. Things like that, certainly we're doing, others are doing. I think probably every management team out there is scrambling to try to figure out what to do. I do think that we have relatively limited exposure, especially with our A&D business. Okay. I guess lastly, can you address the line of credit? I mean, without tapping that, you would have ended the quarter with close to $100 million of cash. I mean, that seems like a pretty good buffer to me, even with all these uncertainties. Maybe you can give a little bit more color there. Yeah, Greg, it's fairly simple. We are expecting that the business is going to grow in the second half of the year. We've talked about the 25% increase year- over- year in defense. In our remarks, we talked about we're getting more confident about that. We want to make sure that we are thinking about allocating capital appropriately. We've got a really attractive credit line. The economy of the world is a little bit bumpy right now. To be able to leverage that credit line to fund some of that working capital that gives us the ability to continue to do all the other things we're doing in the business is why we drew on it. I mean, is there a certain level of cash that you want on the balance sheet as a buffer no matter what? I mean, is there a certain number that you're sort of looking at? There's no magic number. I think we talk a lot internally about being more than adequately capitalized at around $100 million. But again, you have quarters in which you are going to need to invest in working capital or in CapEx that we want to try to make sure that we are funding that appropriately. Yep. Okay. All right. I know it's probably been a while since I've said it, but congrats on the quarter. It was a pretty impressive result. Appreciate it, Greg. Thank you. Thank you. Your next question comes from Ruben Roy of Stifel. Please go ahead. Hey, guys. I also had some issues joining, but I guess the upside is I've got conference call music in my head for a few hours. I guess did you talk about it's great to hear, by the way, and congrats on continued visibility and execution around A&D. Did you give an update on the commercial markets in terms of full year? Has that changed kind of from the way you were looking at that business last quarter? I think you said maybe down 15%-20%, a little up. Those were, I think, the guidelines. Any update there, Joe? No, Reuben. That's still where we think we are. We had a little bit of a better quarter this quarter, particularly in the microfabrication business, as we were able to catch up with some pent-up demand to certain customers. You saw a little bit of a better quarter in micro. The general themes that we have been talking about in the broader commercial businesses are still the same. On top of that, we've got some incremental risk from demand related to tariffs and the like. Broadly speaking, no real change here. Okay. Thanks. Just to follow up on the tariff discussion, some companies—and obviously, there's a lot of moving parts here and uncertainty, and it's been changing pretty rapidly—a lot of companies have been telling us that they potentially could pass through some costs. It does not sound like that is an outcome that you guys are thinking that would be appropriate for your business. Is that correct? If so, again, are there some remedies, or should we be thinking about some level of gross margin impact given that there are some tariffs and costs going up? I mean, even if we kind of stay steady state from here into the second half. Yeah, Reuben, it is a very complex topic, obviously. Certainly, there are places where we can pass on costs to mitigate. There are areas where we can shift production to mitigate. There are even some regulatory aspects of the A&D market where we can mitigate. It is a complex set of topics that we are trying to grapple with, and who knows what the assumption should be for where these tariffs will land. I think the broad outlook that we have, as Joe said, is that we do not see near-term any dramatic effect on the business. Longer-term just depends on how long they last and how it affects the broader economy. That just gives us some pause about uncertainty in the world. I do not think there is anything we can really comment on that is specific in terms of outlook. Joe, do you want to add anything? No. The only thing I would add, Reuben, is that it has caused us to think, widen our margin range a little bit, but it is simply to account for some of that level of uncertainty, not more than that. Okay. Got it. The last question, any update on funded and unfunded backlog progression there as you got through Q1? Yeah. No, Reuben, no major update. I think we're not in the position today where we're going to provide that update quarter over quarter. But I would say that as we continue to execute on the program, we still have the right level of funded backlog plus the unfunded portion. And then as Scott talked about, our activity around responding to proposals continues to increase and be at healthy levels. Generally speaking, we are pleased with the direction of the defense business in terms of backlog execution and the development of pipeline. Helpful. Thank you, Joe. Thank you, Reuben. Your next question comes from Troy Jensen of Cantor Fitzgerald. Please go ahead. Okay. Sorry. I'm still laughing at Greg for the comment, but congrats on the good results here. Thanks, Greg. Hey, for Joe, I heard you say $1.9 million when you're talking about cost of goods sold. Did I hear that? Is that an adjustment to get kind of a one-time event? Yeah. That's the way to think about it. I wouldn't say it's so much one time, Troy. It was just, obviously, in light of what's going on in the world with tariffs, right? We took a really hard look at opportunities this quarter, and we were able to effectively reclaim duties that were paid, and it had a nice benefit to margin during the quarter. We will continue to reclaim duties, but we don't expect it to be quite at that level as we move forward here in the near term. Now, as tariffs either continue, they go up, they change, that will have an impact on what that duty reclaim number is. We wanted to make sure that we call that out specifically to give you a sense for what normalized gross margin would be. That had an impact of call 500 basis points or so. Can you kind of maybe talk us through what you think gross margins could look like here in the middle of the year? Yeah. I think we expect gross margins to continue to expand. If you look at the midpoint of the guidance, right, our product's gross margin is about 30%. That is a slight expansion from where we were in Q1. In Q1, the margin did what we hoped it would do. As we drove higher volumes, our mix improved. As we shipped more A&D product, we recovered in microfab, and we saw some benefit from duty reclaim. As we look to the second quarter, right, it is up a couple hundred basis points. Some of that is continued growth in A&D, right? As we talked about, we do not expect to see the same revenue expansion in microfab. Microfab has pretty good margins. So we think as we continue to drive higher volumes, we'll get better absorption. The mix of business is at the right levels that we would expect directionally our margins to continue to progress and get better as we move throughout the year. All right. Perfect. And just maybe to follow up on Greg's questions too about the line of credit, is there any government customers that require you to have healthier balance sheets? Is that any chance and a reason why you do this too? No. No, not at all. No. Okay. All right. Perfect, guys. All right. Good luck going forward. Thank you. Thanks, Greg. As a reminder, if you wish to ask a question, please press star followed by the number one. Your next question comes from Mark Miller of Benchmark. Please go ahead. Thank you for the question. Just what we're hearing today and previous, it sounds like the second half will be somewhat stronger than the first half. Is that a good assumption? Mark, simply put, yes, it's a good assumption. We expect the second half to be better than the first. One of your competitors reported healthy results in additive manufacturing applications. I'm just wondering how additive business is going for you. We're making good progress in additive, but we are focused on customers in the U.S. and Europe. That's an area where there's more limited growth in the market relative to the markets in some other countries. Thank you. Thank you, ladies and gentlemen. That concludes our question and answer session. I will now turn the conference back over to John Marchetti. Thank you, everyone, for joining us this afternoon and for your continued interest in nLIGHT. We will be participating in several investor conferences this quarter. We look forward to speaking with you during those events and throughout the quarter. Have a great afternoon. This concludes today's conference. Thank you for attending. You may now disconnect your line.
